Which of the following graphs are Eulerian and which are Hamiltonian?Would I be right in saying that the first and second graphs are Hamiltonian and the third is Eulerian,unsure about the 4th? Last edited by dee93 (20130815 22:31:10) #2 20130815 22:39:03
Re: Which of the following graphs are Eulerian and which are Hamiltonian?fourth is eulerian too 'And fun? If maths is fun, then getting a tooth extraction is fun. A viral infection is fun. Rabies shots are fun.' 'God exists because Mathematics is consistent, and the devil exists because we cannot prove it' 'Who are you to judge everything?' Alokananda #3 20130815 23:00:26

Re: Which of the following graphs are Eulerian and which are Hamiltonian?I'm looking now. First is H but not E You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei #5 20130815 23:16:34
Re: Which of the following graphs are Eulerian and which are Hamiltonian?Note: It is possible to be both eg. Four vertices connected as a square. You cannot teach a man anything; you can only help him find it within himself..........Galileo Galilei
